This implies that the low 1,3-BD concentration provided the appropriate solution viscosity to promote the higher mobility of the monomer molecules favoring monodentate coordination with the metal and produced a syn complex (trans-1,4 form) with decreasing as--1,4 configuration [23, 24].
2008) reported the formation of two kinds of silicate on the hematite surface, including a monodentate complexed fraction and an amorphous surface precipitate.
The complex, di(morpholine)titanium dichloride (2a) which was first obtained by serendipity during the synthesis of complex (3a) was successfully synthesized using a chosen synthon and having bidentate ligand will have better catalytic activity than monodentate ligands.
With the increase of grinding time and treatment temperature the amount of bicarbonate- and bidentate-type structures decreases in favor of the carboxylate- and monodentate (Frost, et al.
The material is presented in sections on chiral monodentate phosphorous ligands, chiral bidentate phosphorous ligand diphosphines, mixed P-ligands, hybrid monophosphorous ligands, chiral polyphosphorous ligands, dynamic processes of P-ligands and their complexes, chiral ligands for reactions in alternative media and concepts of heterogenization, P-ligands bound to chiral biomolecules, mixtures of monodentate P-ligands in stereo- and regioselective transition metal catalysis, general methods for the synthesis of chiral trivalent phosphorous compounds, controlling regio- and stereochemistry in metal-catalyzed and metal-mediated reactions with the aid of substrate-bound reagent-directing phosphine groups, characterization of P-ligands and metal complexes, and industrial aspects.
1], which indicates the carboxyl groups of malay acid are coordinated with the metal ions on the surface of SAO-ED phosphors in a monodentate fashion as previously shown (Nakamoto, 1991).
Each of the two apetsc molecules functions as a monodentate ligand, co-ordinating to the Sn atom through the pyrazine ring nitrogen atom and conferring a distorted-octahedral geometry upon tin.
The first, a direct metalation strategy failed to produce chelating complexes, instead generating monodentate NHC-Ir species.
Phosphadiazonium cations with both bidentate- and tridentate-chelating ligands (2 and 3), as well as donor-rich adducts (4) where more than one monodentate ligand coordinates to the phosphadiazonium acceptor have also been prepared.
Furthermore, McKenzie (1983) showed that molybdate sorption by goethite was, on a molar basis, more than twice as large as that of phosphate and this would indicate that a monodentate link to the surface is formed.
